Be it known that 1, Hiinvnr W. BELL, a citizen of the United States ofAmerica, and

,a resident of Boundbrook, county of Somerset, and State of New Jersey,have invented certain new and useful improvements in` Steam PowerPlants, of which the following is a speciiication, reference being hadto the accompanying drawings, forming a partthereof.

.My invention relates to new and useful improvements in steam powerplants and its object is to provide a'steam generator of extremely lightand very simple construction which is capable of working at highefficiency. Another object is to provide a structure of such lightweightthat it is suitable for use with airplanes.

Another object is to combine a generator of my novel constructionwith amotor and a pump in such a way as to cause th-e water supply to theboiler to vary automatically with the speed of the motor.

These and other objects of my invention will be set forth hereinafter,and in order that my invention may be thoroughly understood I will nowproceed to describe the same in the following specification, and willthen point out the novel features thereof in appended claims.

Referring to the drawings:

Figure 1 is a longitudinal section of a boiler made accordingl to andembodying my invention. togetherv with a steam turbine, a condenser, apump and other parts shown diagrammatically in elevation..`

Figure 2 is a transverse section of the boiler. on a larger scale.

Figure is a longitudinal section of a partlof one of my improvedboilers, also drawn on a larger scale than that used in Figure 1. inorder to more clearly show its construction.

Like characters responding parts designates a greater length thandiameter. It is .preferably tapered somewhat so that its form is that ofalong and comparatively narrow truncated cone. 11 is a water inlet pipeconnected` with one end of this pipe coil, and 12 is the steam outletpipe connected with the other end of the pipe coil. .Y The coil iscovered with a heat insulator 13 such as of reference designate cor inall the ligures.

yAt the steam outlet mouth piece 2O is provided which may be madeflaring asshown. 'In the center of this mouth-piece is an oil burner 21to liquid fuel is supplied from a reservoir 22 through a pipe '23 inwhich is a lvalve-24. The reservoir'22 if below the burner is closed andarrranged to be supplied with pressure introduced at 25 The apparatusshown in Figurevl is designed for use in an airplane. In this figure,designates a steam turbine with which'the steam pipe 12 is connected. 31is the exhaust pipe from the turbine to a condenserA 32 the outside ofwhich is a metallic :a'rnun c. FRASER,

end of the structure a whichl vanes of which are curved and inclined asshown, and at the base of which is a water chamber 33. The water chamberis connected by av pipe 34 with the intake of a pump 35 which is drivenby the turbine 30 and the outlet of which is connected with the waterinlet pipe 11.

The turbine is preferably supplied with` reduction gearing within thecasing 36 by means of which its rotor is connected with apropeller'shaft 37. The propeller 38 is preferably vplaced in front ofthe condenser 32 and the intake mouthpiece 20.

I will now 'describe the operation of this a-pparatus.` A 'flame fromthe burner 21 is introduced at one end of the pipe coil 10 and the hotgases therefrom are passed' through the tube formed by this coil. f Theheat is absorbed bythe waterV in the pipe coil' which is thereby turnedinto steam. The hottest end of the pipe coil is at the steam outlet endnot only because the heaty is introduced at this end but because of thecirculation of water and steam inthe coil. The result is thatpractically all of the heat is absorbed and that the gases dischargedfrom the water inlet end of the coil are comparatively cool. Anotherresult is that the water in the pipe coil enters at the condensertemperature and its temperature is gradually raised as it lmoves towardthe steam outlet end. Before it reaches the outlet it is vchanged intosteam and thissteam Aas it advances 'becomes superheated. The

tapered ormv of the pipe coil is preferred as it helps to make' theabsorptionof the heat more complete.

The rotation of the turbine drives the I pump 35 which isiarrangedtosupply water to the pipecoil `as fast as it is needed.` lt'is obviousthat the circulationof water is proportional totthe `speed `of theturbine; The

speed of the turbine `is proportional to the intensity of the ilaineandit followsthat the speed of the turbinefniay be regulated by ad gustingthe valvefQep No other valve is needed,` nor is itonenessarytoAhaveanywater gauge,injector or safety gvalve, `1 The pipe l coil l() ismade `of material of sufficient stri-ingth` to withstand high pressuresand whieh will not burn out when filled with dry steam and subjectedtothe heat of the flame. `When the apparatus is used on an airplane thepipe coil tubeis placed ina fore Vand aftpositiomso that the movement"of ther apparatus through the airfwillfaid in carrying"` `thegaseszpthrough the longtube formedbyl the pipe coil. y The flaring shapeof the mouth-piece 20 assiststhis functionas does also the relativeposition ofthe propeller Sdwhileli acts as a fait yThe gases thusintroduced atene-end of, the tube formed by thepipe Coil,` passgfreelytlierethroughbut are `retarded somewhat by, the taper of the i y, tubeThe/propeller alsof helps to lieep the condenser l 32 cool.;

The apparatusis desirable for `war airplanes as itlhas no delicate`parts `and is not easily 'vulnerable.,` lt` is immune frein ein plosionand the fire rislr is` reduced toa niinil mum becausethe fueloil usedneed not ybe of nor is it necessarily limited to thouse of` gene`erating steam., `lt is well within `the scope of: this invention to` usethe znovel structure as a heater` fori water fo'ri'exaniple, and lintend `no limitations other thanthose imposed bythe appended elaiins.`l l Nhat I elaini is:
